Yeah I understand the issue, it’s basically the complete opposite problem of the gizmo/drag/move tool
The core issue is there is a minimal offset to differentiate multi touch from single touch sculpting.
So either the sculpt starts on where the stylus is, or where you initially pressed it.
Depending on the tool or mode used, you don’t want the same behaviour.
This whole offset thing only makes sense for finger so I should disable it for stylus, trackpad and mouse.
I’ll improve the whole behaviour for next release.
